Hydraulic coal Briquetting machine is the main equipment in the coal forming product line, mainly used for briquetting coal powder, coke powder, sludge, calcareousness, active carbon etc . This kind of machines has solved the problems of the finished ball with low intension, mainly used in the field of metallurgy, chemical and so on. The forming parts is made of alloy steel, passed by heat treatment, hardness testing etc special craftwork.

Hydraulic protection device is a hydraulic pump will be high pressure oil into the hydraulic cylinder, driving the piston produce axial displacement. The piston rod before meet in the head the bearing to meet production pressure requirements. When two pressure roller feeding into too much or between metal pieces, the hydraulic cylinder piston rod press press, hydraulic pump will stop working, overload accumulator pressure changes to the buffer role, overflow valve open to oil, piston rod shift makes the roll gap between increase so that good thing through the pressure roller, the system pressure to return to normal, can protect pressure roller not damaged. This machine can according to the requirements of the density of ball pressure adjustment pressure, production is flexible.
